Copperbase alloys

With their high copper-content, these materials have good electrical conductivity and resistance to corrosion. These properties make them very suitable for such purposes as switch-blades in electrical equipment.

(a) Brass—an alloy containing zinc, roughly 30%, and the remainder copper. A cold-worked material obtainable in both wire and strip form, and which is suitable only for lightly stressed springs.

(b) Phosphor bronze—the most widely used copper-base spring material, with applications the same as those of brass, though considerably higher stresses may be used. (c) Beryllium copper—this alloy responds to a precipitation heat-treatment, and is suitable for springs which contain sharp bends. Working stresses may be higher than those used for phosphor bronze and brass.
